The invention discloses a disposable nanopore biosensor, which comprises a sequentially stacked substrate, an electrode layer and a top cover, and the top cover is provided with micropores with a diameter of 5-200 μm, and the micropores are used for injecting nanopores and phospholipid films. The nanopore biosensor has a simple structure, convenient detection, and low cost. It can be added immediately at the reagent adding section to ensure the stability of the nanopore and phospholipid film itself. Mutual interference of test results among patients improves the accuracy of test results. A manufacturing method of the biosensor is also disclosed. The processing method has simple steps, is easy to operate, can be mass-produced rapidly, greatly reduces the production cost of the nanopore biosensor, and is suitable for mass industrial production and wide application.

The invention discloses a high-strength formwork free of layer separation and a method for manufacturing the high-strength formwork. The high-strength formwork and the method have the advantages that the length directions of battens a are consistent with the growth direction of wood, the height directions of battens b are consistent with the growth direction of the wood, accordingly, sufficient adhesive steeping and mechanical bracing effects can be realized, a core is extremely high in mechanical property in the vertical direction and the horizontal direction and is low in deformation, layer separation phenomena inside the machined core can be prevented, the high-strength formwork is high in modulus, and buckling deformation of the formed formwork can be prevented; the mechanical properties of the formwork can be improved by the aid of continuous fiber reinforcement composite surface layers, the high-strength formwork is light, waterproof and anticorrosion, is high in strength and recycling frequency, and can be easily released from forms, the recycling frequency of the high-strength formwork can reach a hundred at least, accordingly, the service life of the building formwork can be greatly prolonged, and the single-service cost can be reduced.

Provided are a fiber-reinforced building formwork and a preparation method thereof. The fiber-reinforced building formwork comprises a board core and face layers covering the upper surface and the lower surface of the board core; the board core comprises multiple layers of veneers which are bonded into a whole and have wood fibers, and the directions of the wood fibers of the adjacent veneers are mutually perpendicular; each face layer comprises 1-4 fiber-reinforced prepreg sheet layers which are connected into a whole in a composited mode, each fiber-reinforced prepreg sheet layer is formed by compositing fiber products and high-molecular resin, and each face layer and the board core are connected into a whole through a bonding layer. After the building formwork is boiled for two hours in boiling water in a pressure cooker and cooled for one hour at room temperature, the retention rate of the static bending intensity is at least 90%, and the retention rate of the static bending modulus is at least 90%. The formwork is excellent in mechanical property, good in waterproof and breakage-proof property and long in service life, and the per-use cost of the formwork is reduced; use of wood is avoided, and therefore the formwork is more environmentally friendly.

The invention provides an SMC compression molding process for interior and exterior corner templates of a building. The process comprises the following steps: cutting an SMC material into sheets with certain sizes and weight according to the sizes of interior and exterior corner templates; feeding the cut SMC material into interior and exterior corner template dies according to feeding requirements; carrying out compression molding on the SMC material in the interior and exterior corner template dies at certain pressure and temperature; and carrying out die-opening to take out prepared interior and exterior corner templates. The process provided by the invention can improve apparent quality and mechanical properties of the prepared interior and exterior corner templates; and the prepared interior and exterior corner templates have the advantages of repeated usability, light weight, aging resistance, simple splicing of templates, high efficiency and low cost for single usage.
